Jackson Boulevard project on track for completion this year

Jackson Boulevard

SPEARFISH, SD – The transformation on Jackson Boulevard since construction began in 2019 is evident, with the project on track for completion later this year.

Spearfish Assistant Public Works Director Adam McMahon explained the major goals of the project:

  1. Roadway rehabilitation: The former asphalt pavement surface on Jackson Boulevard reached a point where it was in need of rehabilitation through patching, crack repair, and a full-width mill and asphalt overlay. 
  2. Utility infrastructure replacement: Sections of former water and sewer mains under the roadway were in need of replacement due to age. The storm drainage capacity was limited and needed significant upsizing.
  3. Safety: Adding center turn lanes, raised medians, traffic calming measures, new improved street lighting, bicycle lanes, signalized pedestrian crossings, and replacing non-ADA compliant handicap ramps improved the corridor as a welcoming, inviting, safe street for all users.
  4. Gateway corridor enhancements/streetscaping (i.e. aesthetics/beautification): Jackson Boulevard is a main arterial road providing access from the Interstate 90 corridor to the City center, parks, businesses, homes, and Black Hills State University. 
  5. Preservation/enhancement of community character
  6. Economic development

The total project area stretches from Exit 12 to University Street, with construction this season focusing on the area from approximately Canyon to University streets. Within this project area, the east end of the project is nearly complete, McMahon said, with street lighting and landscaping all that remains to be finished. Crews have completed the underground utilities, curb, gutter, and asphalt milling on the west end of the project area.

New curb and sidewalk are complete on both sides of the bridge spanning Spearfish Creek, with work on the asphalt overlay ongoing. Completion of the sidewalk, landscaping, pavement marking, and lighting will continue through the fall. The new bridge railing is scheduled to be completed in October and installed shortly thereafter. 

McMahon reminded motorists to slow down through the work zone, be patient, and be prepared for delays. As work continues, traffic configurations change, and motorists need to be aware that the route they took previously may have been reconfigured the next time they travel through the construction zone. Be on the lookout for directional signs guiding motorists through the project area.

McMahon added that people may have noticed missing streetlights along the project area. Unfortunately, like so many others, this project has been impacted by supply chain and manufacturing issues. The manufacturer is working to deliver the proper streetlights once they are available.

The overall contract completion date for the project is Nov.15, 2021, and the contractor is on schedule to complete the project by the deadline, McMahon said.

“The Hive” sculpture, created by local artist Dale Lamphere and commissioned by Black Hills State University, is scheduled to be set in the roundabout at the intersection of Ames Street and Jackson Boulevard on Sept. 7, with the sign for Black Hills State University to be set Sept. 9.
